not a marathon but a half do you think it is possible to do a half on 3 runs a week.
Sunday run 9/11 miles@ 9 min per mile
2 runs of 5/7 miles doing steady run (although I'veput mileage I do these 2 runs in km efforts warm up then each km@4 1/2 min effort 1-2 mins rec)
I also bike to and from work 5 days a week 12 mile each day
